S-SLB-15-25NIR2

It is the product that was reduced by one rank from the surface quality of Plano Concave Lens (SLB-N).
It can be used in an optical system such as observation or lighting applications that high surface quality is not required.

◦It has the same specification of Plano Concave Lens (SLB-N) except the surface quality. Unless a laser is used for high-precision experiments, it is recommended.
◦There are two types of lens. One is a Plano concave lens with low spherical aberration and the other is a biconcave lens that is possible to shorten the focal length by a large refraction.
◦In addition to uncoated products, there are three types of anti-reflection coating for visible, near-infrared, and infrared.
